Page 14 Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

To assist in the safe and secure storage of fuels, hazardous materials and hazardous waste, the following general guidelines for storage areas/facilities will be considered:

• Design of storage areas shall be in compliance with the National Fire Code, where appropriate.

• Drainage into and from storage areas shall be controlled in order to prevent leaks or spills from migrating off-site and to avoid run-off from entering the storage areas.

• Storage areas shall have controlled access. Only authorized and trained personnel shall have access to storage areas.

• Leaking or deteriorated containers shall be removed and their contents transferred to a sound container.

• Storage areas shall be adequately signed indicating that there is to be no smoking, no sparks or flames and hazardous materials/wastes are stored therein.

• Storage locations shall be clearly defined and marked to prevent damage of storage drums and containers in the event they are covered by snow.

• Incompatible materials shall be segregated by chemical compatibility within the storage area to prevent contact between materials in the event of a release.

• Storage containers will be clearly labelled, visible to all staff and contractors. • Storage areas shall be located at least 100 m from surface water and on a low-permeability area, where possible.

• Storage areas shall be readily accessible for fire fighting and other emergency procedures.

• Storage areas shall be adequately ventilated to prevent the build up of noxious or toxic vapours.

• Secondary containment or an adequate spill collection system shall be installed to allow for the containment of at least 110% of the largest container or tank volume within the contained area, plus 10% of the aggregate capacity of all other containers or tanks (Details on the bermed waste storage area are provided above and in Figure 2-6). • Secondary containment shall be kept free of debris, water accumulation and snow.

• Storage areas and associated secondary containment shall be protected from the elements, where possible. In case this is not feasible, the secondary containment volume shall be large enough to allow for any precipitation (rain, snow, and storm water run-on) that may enter containment systems located outdoors, in addition to the required containment volume for stored materials. In addition, sufficient capacity to handle sprinkler water and other water from fire protection efforts will be provided.

• Storage areas shall be constructed, or provided with barriers, to protect containers from the environment and physical damage.

• Adequate spill and emergency response equipment shall be installed at each storage area (i.e., spill control, fire protection, etc.). A list of spill control equipment is provided in the Spill Response Plan.

• The site shall not be used for long-term storage of hazardous waste (i.e., in excess of one year).

3 SPILLS

3.1 WHAT IS A SPILL?

For the purposes of this SCP, a spill is defined as an accidental release of a contaminant into the environment that has the potential for adverse impact.

3.2 MATERIALS & REPORTABLE SPILLS ON SITE

According to the NWT Spill Contingency Planning and Reporting Regulations, where there is a reasonable likelihood of a spill or accidental release (including in frozen conditions) in an amount equal to or greater than the amounts set out in Table 3-1, the spill must be reported to the NWT 24- HOUR SPILL REPORT LINE at 867-920-8130.

The Plant Operator, or their designate, is responsible for reporting spills at the Facility. The Plant Operator must be notified immediately of any spill, regardless of quantity to land or water.

As a precaution, if there is any doubt as to whether the quantity spilled meets the minimum reportable thresholds listed in Table 3-1, the spill incident shall be reported to the NWT 24-HOUR SPILL REPORT LINE.

The Facility maintains a detailed log of all spills of hazardous materials, including non-reportable spills. As part of Facility’s overall environmental management system, procedures will be implemented to encourage all site workers to communicate non-reportable spill incidents to the Plant Operator.

If there is a spill of any substance into a water body or watercourse which may affect or endanger users of the Snare River, the Emergency Preparedness Plan should be implemented.

3.3 SPILL PREVENTION MEASURES

The first step in hazardous materials spill response is to take steps to prevent the spill from occurring. Planning for emergency situations is imperative, due to the nature of the materials stored on site as well as the remoteness of the site. Along with the preventative measures outlined below, adequate training of staff and contractors is paramount.

The following general preventative measures are in place to minimize the risk and impact of a potential spill or release:

• Prior to starting work at the Facility, all employees and contractors are required, as a minimum, to go through an orientation session to familiarize themselves with this SCP, the hazardous materials present at the Facility and the Facility spill response procedures; • All site staff are trained on the safe handling, transfers and dispensing of fuels at the facility. Safe practices include, but are not limited to, required PPE, constant attendance during fuelling operations, only fuelling when spill kits are available nearby, and awareness of location of pump shut-offs and emergency shut-offs. Records of training are maintained; • The main fuel and hazardous materials storage and dispensing areas are located more than 100 m from the Snare River; and/or are stored indoors where spills are not likely to exit from the storage building; • Spill kits are provided wherever fuel is stored, used and transferred. The spill kits and their contents are regularly inspected to ensure that adequate supplies are available; • Fuel and chemical storage areas are provided with secondary containment; and, • The Plant Operator conducts daily visual inspections of the facility to check for leaks or damage to the fuel storage containers, as well as for stained or discoloured soils around the fuel and chemical storage areas. Storage areas are kept clear of snow and debris.

NTPC also supports the following general principles for spill prevention:

• Train workers in the use of safe work procedures for hazardous materials, and procedures to clean up spills; • Encourage workers to take reasonable measures to prevent spills; • Provide access to up to date MSDS for all hazardous materials; • Conduct inspections of fuel/chemical storage areas; • Keep drums/containers sealed or closed, except when removing or adding contents; • Avoid over filling drums/containers; • Place drums/containers within a suitable form of secondary or spill containment; • Keep storage areas secure from unauthorized access; • Segregate incompatible materials; • Ensure storage areas are adequately protected from weather and physical damage;

Page 20 Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

• Provide adequate spill response materials at storage areas; • Develop and implement good environmental work practices such as the use of oil drip trays and absorbents for servicing vehicles; • Regularly inspect, clean and maintain machinery which may operate near or perhaps in water; and • Regularly inspect storage areas.

4 RESPONSE ORGANIZATION

4.1 RESPONSE ORGANIZATION

The flow chart depicted in Figure 4-1 identifies the response organization and the chain of command for responding to a spill. In accordance with the action plan described in Section 5, the response organization details the roles and responsibilities of each party involved in the spill and their contact information, including the 24-hr phone numbers for the responsible personnel. Note that post Devolution (as of April 1, 2014), the Government of the Northwest Territories (GNWT) department of Environment and Natural Resources (ENR) has taken over the duties of Indian and Northern Affairs Canada (INAC) Inspectors for issued water licenses. ENR’s North Slave region is responsible for spills under NTCP’s water license.

5 ACTION PLAN

5.1 POTENTIAL DISCHARGE EVENTS – WORST CASE SCENARIOS

In Table 5-1, a list of potential discharge events, with associated discharge volumes and directions is presented for the primary hazardous materials stored on-site. The most likely discharge volume is indicated and the spill clean up procedures will focus on the spills of this quantity. A worst case scenario is also presented. Specific discharge rates are not indicated for each fuel type, as these would vary from a few minutes to several hours, based on the source of leak or puncture.

5.2 POTENTIAL ENVIRONMENTAL IMPACTS OF SPILLS (INCLUDING WORST CASE SCENARIO)

Overall, for all hazardous materials discussed below, impacts are lower during winter as snow is a natural sorbent and ice forms a barrier limiting or eliminating soil or water contamination, thus spills can be more readily recovered when identified and reported.

5.2.1 Flammable and Combustible Liquids

Flammable liquids have flash points below 37.8°C, evaporate quickly, and within a short period of time can reach high vapour concentrations in air. Flammable liquids at the Facility include, but are not limited to, gasoline and aviation fuel. Although not stored on site, aviation fuel will be present in helicopters landing at the Facility. Spills of flammable liquids represent an extreme fire and explosion hazard if vapour concentrations exceed the lower explosion limit (LEL). They are generally harmful if inhaled and can also be absorbed through the skin.

Combustible liquids such as diesel fuel have a flash point above 37.8°C but below 93.3°C and are not fire hazards at room temperature. The principal hazard from non-flammable, volatile liquid spills is exposure to the vapour by inhalation or skin absorption.

The most common flammable and combustible materials stored and handled on site are liquids such as gasoline, diesel, and waste oils. For the purposes of spill response actions, lubricants and motor oil have been included with the flammable and combustible compounds given their petroleum hydrocarbon based nature. Glycol product and used glycol spills will also be handled as flammable/combustible materials.

With the exception of very small quantities of fuel and glycol required to maintain the generators, all hazardous materials and wastes are stored and managed at the airport facility. Activities such as burning on ice and the unscheduled releases of water are not anticipated at the Snare Hydroelectric Facility.

Gasoline Environmental impacts: Gasoline may be harmful to wildlife and aquatic life. It is considered a carcinogen and does not readily biodegrade. Gasoline is quick to volatize. It has a relatively low solubility in water and is less dense than water, and hence can form a layer of non-aqueous phase liquid (NAPL) floating on top of water if released in sufficient quantities. Runoff into water bodies must be avoided.

Worst case scenario: 60,000 L double wall tank failure and contents seeped into surrounding soil and water bodies. This could cause illness or death to aquatic life and indirectly affect wildlife feeding from the land and water.

Page 30 Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

Diesel Environmental impacts: Diesel may be harmful to wildlife and aquatic life. It is not readily biodegradable. Diesel burns slowly and thus the risk to the environment is reduced during recovery as burn can be more readily contained compared with volatile fuels. It has a relatively low solubility in water and is less dense than water, and hence can form a layer of NAPL floating on top of water if released in sufficient quantities. Runoff into water bodies must be avoided.

Worst case scenario: AST secondary containment failure or seam/joint failure and contents seeped into surrounding soil and water bodies. This could cause illness or death to aquatic life and indirectly affect wildlife feeding from the land and water.

Aviation Fuel Environmental impacts: Aviation fuel may be harmful to wildlife and aquatic life. It is not readily biodegradable. Aviation fuel is quick to volatize. It has a relatively low solubility in water and is less dense than water, and hence can form a layer of NAPL floating on top of water if released in sufficient quantities. Runoff into water bodies must be avoided.

Worst case scenario: Aircraft crashed on site, release fuel from its fuel tank. The spilled aviation fuel has the potential to seep into surrounding soil and water bodies. This could cause illness or death to aquatic life and indirectly affect wildlife feeding from the land and the water.

Oil Product, Used Oil and Miscellaneous Oils/Grease Environmental impacts: Raw oil product, used oils may be harmful to wildlife and aquatic life. Oil products are not readily biodegradable. These compounds generally have a low solubility in water, thereby separating into NAPL. Runoff into water bodies must be avoided.

Worst case scenario: All storage drums punctured or open simultaneously and contents seeped into surrounding soil and water bodies. This could cause illness or death to aquatic life and indirectly affect wildlife feeding from the land and water.

5.2.2 Compressed Gases

Compressed gases such as propane and acetylene are stored in relatively small quantities at the Facility. They are flammable and can ignite and explode if exposed to an ignition source. Vapours cannot be contained when released, and it is important that personnel withdraw immediately from any such release. If tanks are damaged, the gas should be allowed to disperse, with no attempt at recovery.

Compressed gas spills/leaks can generally be divided into two categories. The first are those leaks which occur away from the gas cylinder in lines, tubing, or apparatus. These types of leaks can generally be stopped by closing the main cylinder valve, if it is otherwise safe to do so. The second category of leak occurs at the cylinder itself, and cannot be stopped by closing the cylinder valve.

Page 31 Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

In some cases it may not be possible to close a cylinder valve due to age or poor condition, and as such, this situation falls into the second category of gas leak. All leaking gas cylinders are considered an emergency if the leak cannot be stopped by closing the cylinder valve. Leaks of oxygen, flammable gas, or toxic gas are especially dangerous.

Propane Environmental impacts: Propane is extremely volatile and very flammable, and thus it represents a health hazard for fire and explosion. Propane is not considered toxic or harmful to wildlife or aquatic life or the environment in general. Propane is heavier than air and may travel a considerable distance to an ignition source. Cylinders may vent rapidly or rupture violently from pressure when involved in a fire situation.

Worst case scenario: All cylinders are punctured or fail simultaneously and contents discharge into the surrounding environment and ignite leading to a fire and/or explosion. This could cause serious environmental impacts in the immediate surroundings. Safety during emergency response to a propane spill is of the utmost concern.

Acetylene Environmental impacts: Acetylene is not especially toxic to wildlife, aquatic life or the environment in general. Depending on the manufacturing process it can contain toxic impurities such as traces of phosphine and arsine. Acetylene is extremely volatile and very flammable, and thus it represents a health hazard for fire and explosion.

Worst case scenario: All cylinders are punctured or fail simultaneously and contents discharge into the surrounding environment and ignite leading to a fire and/or explosion. This could cause serious environmental impacts in the immediate surroundings. Safety during emergency response to an acetylene spill is of the utmost concern.

Oxygen Environmental impacts: Oxygen is not considered toxic or harmful to wildlife or aquatic life or the environment in general. Highly concentrated sources of oxygen promote rapid combustion and therefore are fire and explosion hazards in the presence of fuels.

Worst case scenario: All cylinders are punctured or fail simultaneously and contents discharge into the surrounding environment and promote ignition of flammable material leading to a fire and/or explosion. This could cause serious environmental impacts in the immediate surroundings. Safety during emergency response to an oxygen spill is of the utmost concern.

Page 32 Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

5.2.3 Infectious Substances / Sewage

Infectious substances such as biological wastes from the sewage treatment plant are potentially hazardous when inhaled, ingested, and in contact with the eye. Initial preventative measures include wearing appropriate personal protective equipment (impermeable gloves, eye protection, and respirators appropriate for the size and type of spill). In the event of a spill on land, the material will be contained by diking or barriers. Liquids spilled in water will be dammed and diverted. Where raw sewage is spilled, the spill material can be sent to the sewage treatment system to be processed.

Sewage Environmental impacts: Microbes in raw sewage can enter the body via the nose, mouth, open wounds or by inhalation of aerosols or dusts. Raw sewage contains biological agents such as bacteria, viruses, fungi and parasites (e.g., tetanos bacterium Clostridium tetani, the parasitic worm Leptospira icterohaemorrhegiae, the Hepatitis A virus (HAV), protozoan parasites Giardia and Cryptosporidium, and bacteria E.coli) that can cause serious illness and even death. There is also a risk from contamination with unknown chemicals (such as solvents, fuels, general household cleaning chemicals) discharged with grey water and from toxic, irritant, asphyxiating or flammable gases in confined spaces (e.g., septic tanks). The risk of exposure when handling sewage can be reduced significantly by effective and immediate clean-up and by taking appropriate safety precautions.

5.3 SPILL PROCEDURES

The following flowchart (Figure 5-1) outlines the overall steps to be taken in the event of a spill. The detailed description of what is required at each step is outlined in the Spill Response Procedure (Section 5.3.1).

5.3.1 Spill Response Procedures

STEP 1 – Ensure safety, identify spill and assess hazards and risks

Initial actions for spills include ensuring personnel and site safety. Ensuring personnel and site safety is the responsibility of all parties, particularly the first responder who has the most knowledge of the spill. Upon the identification that a spill or release has occurred, the first responder shall perform the following:

• Ensure safety of yourself and all personnel; • Alert all persons in the immediate area that a spill has occurred; • Characterize Spill: • identify the material and its hazard potential (refer to MSDS if necessary);

Page 34 Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

• identify the source of the spill; and,

• identify the amount and the extent of the spill.

• Assess the spill hazards and risks to persons, property and the environment.

Note: Where life or property is in danger, there is an emergency. Get help. Contact the local fire department, police or municipal authority.

STEP 2 – Notify the Plant Operator / On-Scene Coordinator

After the details about the spill are known, the First Responder shall contact the Plant Operator / On-Scene Coordinator who will activate the SCP.

Note: The Plant Operator / On-Scene Coordinator is to immediately contact the Manager, Plant Operations (or NTPC On-site Representative) and/or Director, Health, Safety & Environment if a spill response exceeds the abilities/capabilities of onsite personnel or equipment and/or if there is a high potential of adverse effects to offsite areas and/or sensitive ecological or human receptors. See Figure 4-1 Organizational Communication Flowchart.

STEP 3 – Secure Area and Obtain Personal Protective Equipment

Upon determining what the spilled product is and its hazard potential, the On-Scene Coordinator shall perform the following:

• Keep all personnel not directly involved with the spill response away from the spill area. • Ensure all personnel involved in the spill response are aware of the hazards of the spilled product, spill response and the environment. • Obtain the required response equipment and PPE for the spill response team members. Personnel will not be able to use the response equipment and PPE until they have been trained on its proper use and limitations.

STEP 4 – Stop Spill

If Safe to do:

• Locate the spill source and stop it/shut it off (e.g. turn off pump, close valve, turn off equipment, turn off-power source). • Shut off ignition sources. • Shut off operating equipment. • Attend to the injured (refer to MSDS for first aid response).

Page 35 Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

• If a spill occurs from the wall of a tank and cannot be stopped, transfer the product from the leaking tank to another storage tank in order to reduce the amount spilled. Use secondary containment (drum or pail) to catch the product and prevent further impact where possible.

STEP 5 - Contain Spill

• Determine the direction and speed the spill is moving. Determine what is causing the spill to move (wind, gravity, water, etc.); • Determine what will be affected by the spill (environment, property); • Determine the best location where the spill can be contained with available staff and equipment; • Determine actions to reduce risk/damage to human health, the environment and property as a result of the spill. • Contain the spill. Refer to Appendix E for containment methods. Refer to Section 6 and Appendix F for a list of spill response equipment. • First attempt to contain the spill so as to prevent its entry directly into a potable water source, water body or into a ditch or conveyance that eventually discharges in to a water body. • Should the spill reach the water, IMMEDIATELY shut down the generator and stretch a sorbent boom across at the tailrace narrows, and use sorbent pads and booms to collect product from the water’s surface. • Prepare a contingency plan in case the spill gets out of control of present staff and equipment. Note: Do not contain compounds (e.g. gasoline, aviation fuel) if vapours might accumulate and ignite – allow them to volatilise.

STEP 6 - Report Spill

• Completely fill out a Spill Report Form (Appendix A) and fax to the 24-HOUR SPILL REPORT LINE, Health, Safety & Environment Department, and the Manager of Plant Operations as specified on the form. Form also available on PowerLine. • For large fuel spills follow the Fuel Spill Calculations Procedures (Appendix B) to determine the spill volume. • Refer to Section 5.3.2 for additional information on spill reporting procedures. • Contact GNWT ENR at 873-7181 (see also Table 4-3) • GNWT Lands Inspector at 767-9188

STEP 7 - Spill Recovery / Cleanup and Disposal

• Prior to initiating clean up and disposal procedures, the appropriate regulatory body and the Director, Safety & Environment must approve the procedures. • Refer to Sections 5.6 to 5.9 of this SCP for information on product recovery / clean up, storage, disposal, and site clean up procedures. • Upon completion of clean up fill out a Spill Update Form (Appendix C) and fax as directed on form. Form also available on PowerLine.

Page 36 Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

STEP 8 – Spill Incident Investigation

• Plant Operator in consultation with Director, Health, Safety & Environment and Manager Plant Operations to conduct an internal review of the spill cause, effects, and effectiveness of the SCP procedures. • Investigation findings to be used to develop corrective actions.

STEP 9 - Close Spill File

• The Director, Health, Safety & Environment will follow up with the appropriate regulatory body to ensure that a satisfactory clean up and/or remediation of affected areas has been completed.

5.3.2 Spill Reporting Procedures

NTPC policy is to report all spills of fuel or hazardous materials adjacent to or into a water body, regardless of quantity, or spills of hazardous materials over 5 litres unless the minimum quantity specified in the NWT Spill Contingency Planning and Reporting regulation is more stringent (i.e., less than 5 L).

A person reporting a spill shall give as much of the following information as possible:

a) Date and time of spill. b) Location of spill. c) Direction the spill is moving. d) Name and phone number of a contact person close to the location of spill. e) Type of containment spilled and quantity spilled. f) Cause of spill. g) Whether the spill is continuing or has stopped. h) Description of existing containment. i) Action taken to contain, recover, clean up and dispose of spilled contaminants. j) Name, address and phone number of person reporting spill. k) Name of owner or person in charge, management or control of contaminants at time of spill.

Reporting shall not be delayed because of the lack of knowledge of any of the factors listed. No person shall knowingly make a false report of a spill or potential spill.

It is the responsibility of the Plant Operator to report the spill to the 24-HOUR SPILL REPORT LINE at (867) 920-8130 and to the Department of Lands Inspector (867)-767-9188, and they shall perform the following:

1. Fill out the SPILL REPORT Form as completely as possible. The form is available through the NTPC Intranet PowerLine (Appendix A). If required for a large fuel spill, follow the Fuel Spill Calculation Procedures (Appendix B) to determine the spill volume. 2. Fax or phone in the Spill Report Immediately to the 24-HOUR SPILL REPORT LINE at:

Page 37 Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

Fax: (867) 873-6924 Phone: (867) 920-8130

NOTE: Collect telephone calls can be made by informing the Operator that you wish to report a spill. RCMP communications may be used if other means are not available.

3. Fax Spill Report to Health, Safety & Environment Department and Manager, Plant Operations. See phone list (Table 4-1) for contact info.

5.4 DECONTAMINATION

Adjacent to, or near the spill zone, decontamination stations will be established. The decontamination stations will be constructed so that personnel will pass through the station prior to leaving the contaminated area. The decontamination stations may be bermed and lined with plastic sheeting. Washing solutions may be placed near the spill site. All solutions in tubs will be clearly marked.

Note: Notwithstanding the preceding, all applicable health and safety rules, regulations, and legislation will be adhered to.

5.5 CONTAINMENT

The following section describes various methods which may be employed to contain a spill to land, water, ice or snow.

5.5.1 Containment of Spills on Land

Spills on land include spills on rock, gravel, soil and/or vegetation. It is important to note that soil is a natural sorbent, thus spills on soil are generally less serious then spills on water as contaminated soil can be more easily recovered. Generally spills on land occur during the late spring, summer or fall when snow cover is at a minimum. It is important that all measures be undertaken to avoid spills reaching open water bodies.

The following methods are described in more detail in Appendix E:

• Dykes • Trenches • Dams

Page 38 Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

5.5.2 Containment of Spills to Water

Spills on water such as rivers, streams or lakes are the most serious types of spills as they can negatively impact water quality and aquatic life. All measures need to be undertaken to contain spills on open water.

The following methods are described in more detail in Appendix E:

• Booms • Weirs • Barriers

5.5.3 Containment of Spills On or Under Ice

Spills on ice are generally the easiest spills to contain due to the predominantly impermeable nature of the ice. For small spills, sorbent materials are used to soak up spilled fuel. Remaining contaminated ice/slush can be scraped and shovelled into a plastic bag or barrel. However, all possible attempts should be made to prevent spills from entering ice covered waters as no easy method exists for containment and recovery of spills if they seep under ice.

The following methods are described in more detail in Appendix E:

• Dykes • Trenches • Snow Fence and Sorbent Barrier • Burning • Ice Slotting • Vertical Barriers

It should be noted that burning on ice is not anticipated to occur and in the event that this mitigation method should be chosen (as an emergency response), authorization from GNWT ENR Inspectors will be secured prior to any action (refer also to Section 5.8.2).

5.5.3.1 Containment of Spills on Snow

Snow is a natural sorbent, thus as with spills on soil, spilled fuel can be more easily recovered. Generally, small spills on snow can be easily cleaned up by raking and shovelling the contaminated snow into plastic bags or empty barrels, and storing these at an approved location.

The following methods are described in more detail in Appendix E:

Page 39 Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

• Dykes 5.5.4 Barrel Containment

If liquid is leaking from a barrel and the leak cannot be plugged nor are there overpack drums on hand, the barrel can be rolled onto its side so that the leaking area is at the highest point, and will therefore no longer leak. A leak may be plugged with wooden wedges wrapped with a cloth or heavy-duty tape, or by placing an inner tube around the barrel over the leak. The inner tube can be tightened by twisting it with a rod or stick. All of these methods are to be used as temporary seals only. The liquid needs to be transferred into a new barrel or storage tank as soon as possible to prevent further contamination.

5.6 RECOVERY / CLEANUP

In most cases, spill recovery / clean up is initiated at the far end of the spill and contained moving toward the centre of the spill. Fuel recovery methods generally include direct suction, mechanical removal, and the use of sorbent material. A water spray mist may be used to herd the fuel to an area for collection.

All materials mentioned in this section are available in the spill kits located at the Facility. Following clean up, any tools or equipment used will be properly washed and decontaminated, or replaced if this is not possible.

5.6.1 Direct Suction Equipment and Techniques

Direct suction methods include the use of vacuum trucks, portable pumps, or shop vacuums. Vacuum cleaners or portable pumps can be used to directly recover materials from damaged containers or from thick slicks on water.

Shop vacuums are suitable for small spills if a power source is available. Commercial skimmers are available for attachment to vacuum sources. These skimmers serve to skim floating product from the water surface while reducing the amount of water recovered. Suction screens may be required to prevent hose plugging by floating debris and to prevent pump damage.

Care should also be taken to prevent the uptake of water in order to minimize both the final volume of material that requires disposal and to prevent emulsification of oil and water. Once removed from the water body, however, water and oil can be separated using gravity separation. Valving on vacuum trucks can be used for water/oil separation, or a drum separator may be readily constructed using a 205-L (45-gallon) drum and plumbing hardware (Figure 5-2).

CAUTION: All containers used for the recovery of fuel must be grounded due to the potential for static-electricity build-up and fire.

Page 40 Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

Figure 5-2: Improvised Oil-Water Separator Drum

Prior to the release of any water to the environment, it will be analyzed by a Canadian Association of Laboratory Accreditation (CALA) accredited laboratory to verify that the water does not contain petroleum hydrocarbons (PHC). Only water free of detectable PHC will be released to the environment.

5.6.2 Manual and Mechanical Recovery

Manual recovery by use of hand tools (e.g. cans, buckets, shovels, rakes) is an effective means of recovering fuel from small spills or from areas that are inaccessible to larger equipment. This is often the only method available, and in some cases is preferred as it causes the least amount of damage to an area.

Mechanical recovery using heavy construction equipment can be used in some cases for recovery and loading of material for disposal. Caution must be used when operating such equipment around a spill site. In some instances, more damage can be caused from the operation of the equipment than from the spilled product. Escaping petroleum vapours may also be present and pose the danger of explosion and fire.

Page 41 Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

5.6.3 Sorbent Material

Sorbent materials are commonly used for final clean up and recovery of small amounts of oil or to remove oil in places that are inaccessible to other means of recovery. They are effective in recovering thin as well as thick layers of oil, however large volumes of sorbent are often required. Used sorbent materials are to be placed in drums for future disposal.

The types of sorbent materials available at the Facility and generally available for spill response are listed in Section 6 and Appendix F.

Snow and soil can be used as effective sorbent materials. Once mixed, the oil in snow or soil mixture can be shovelled or picked up using construction equipment and taken to a suitable treatment site.

5.7 STORAGE

Storage is required:

• if a suitable location for disposal cannot be found; • if climatic conditions do not permit disposal at the time of clean up; • if the selection of a disposal option requires further assessment; or, • if transportation to a treatment/disposal facility is dependent on the availability of a suitable transport vehicle. Storage options generally consist of pails, drums, tanks, berms, or pits. The specific type of storage needed is dependent on the volume of recovered material, the degree of contamination of the water and/or soil, the properties of the spilled product, and the duration of storage required.

5.7.1 Vehicle Storage

Vehicles suited for the storage of recovered fuel are tank trucks, vacuum trucks, dump trucks, flat bed trucks, sled-mounted tanks, and transport trailers. Tank trucks may be used to separate oil and water by emptying the water from the bottom of the tank. Tank trucks typically hold up to 20 cubic metres (m3), while vacuum trucks typically hold around 16 m3.

Flat bed trucks and transport trailers are suitable for carrying tanks and drums braced on pallets.

5.7.2 Open-Topped Tanks

Open-topped tanks such as plastic-lined swimming pools with capacities up to 20 m3 may be quickly assembled on firm, level ground. They may be fed by several hoses at once and can store both liquids and solids. These should be used only for short-term storage when storing fuel.

Page 42 Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

5.7.3 Drums

Tanks and drums, which are available in all communities, may be used for temporary storage of fuel.

5.8 DISPOSAL

Disposal or destruction of recovered fuel is needed to eliminate the risk of further contamination from the recovered fuel. No decision, except under emergency conditions, should be made until approval has been obtained from the Director, Safety & Environment and appropriate government agencies. The 24-HOUR SPILL REPORT LINE should be used to initiate such requests and a follow-up report should describe the disposal methods used. After Devolution in the NWT, on April 1, 2014, the lead agency responsible for inspections under issued water licenses is the GNWT ENR. Accordingly, NTPC will work closely with GNWT ENR inspectors.

5.8.1 Salvage and Recycle

Recovered diesel and lubricating oil may be reused directly as a low-grade heating fuel in waste oil furnaces.

5.8.2 Fuel Burning

Open burning of spilled oil products is not an acceptable disposal method. Open burning is prohibited except in the case of an extreme emergency. Only appropriate government regulators can authorize controlled or open burning of spilled products. This option will only be considered in extreme emergencies (i.e. when humans or environmental receptors are in grave danger of extensive contamination) and following consultations between the Director, Health, Safety & Environment and the GNWT ENR.

5.8.3 Glycol Spill Response

As noted above, only very limited quantities of glycol (ethylene glycol) are used and stored at the Facility (for use in the generators). Details on amounts, storage and potential spill scenarios are provided in tables 2-1, 2-2 and 5-1.

Studies have shown that ethylene glycol is readily biodegradable under both aerobic and anaerobic conditions in soils and water. Research has also demonstrated that ethylene glycol has a low toxicity to aquatic organisms. Accidental glycol spills on the ground (and in the snow) will be treated as described for PHC in the sections above. Considering the small quantities stored and the protective measures at the storage locations, it is considered unlikely that accidentally spilled glycol will enter ground or surface water through runoff processes.

Page 43 Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

5.9 SITE RESTORATION

For spills of reportable sizes, once a spill has been contained, the Director, Health, Safety and Environment will consult with the GNWT ENR Inspector assigned to the file to determine the level of clean up required. The Inspector may require a site specific study to ensure appropriate clean up levels are met. Methods that may be considered include natural biodegradation of oil and replacement of soil and re-vegetation (see below for further details).

Upon completion of spill clean up efforts, the Plant Operator will conduct an internal review of the spill cause, effects and SCP procedures and then fill out the Spill Update Form (Appendix C) and fax it as directed on form to the Director, Health, Safety and Environment and Manager, Plant Operations. The Spill Update Form also available on NTPC Intranet PowerLine.

5.9.1 Natural Assimilation (Biodegradation) and Revegetation

Oil can be degraded naturally by microorganisms under proper temperature and nutrient conditions. Tilling the affected soil to increase exposure of the soil organisms and oil to oxygen can also be beneficial. The utilization of natural assimilation to treat, in whole or in part, soils affected by spilled oils requires the approval of government agencies.

5.9.2 Replacement of Soil

In some cases, it is necessary to replace contaminated soil with clean soil. This can include grass or sod on the upper layer of soil. Before contaminated material is removed, regulatory agencies must be contacted regarding acceptable disposal sites. Spills that take place on tundra receive special attention due to the presence of sensitive soils and plants. Replacing contaminated tundra may be more detrimental to the area than allowing the contamination to naturally degrade.

Shovels, front-end loaders, backhoes, and dozers may be used to excavate contaminated soil.

6 RESOURCE INVENTORY

The facility maintains numerous resources to support spill response including on and off-site resources.

6.1 ON-SITE RESOURCES

8 TRAINING PROGRAM

NTPC conducts site orientations that include SCP and spill response equipment awareness. Both employees and contractors must complete the NTPC Site Orientation upon entering the Facility for the first time and prior to conducting work. The NTPC Plant Operator provides the site orientation, which provides an overview of this SCP, the locations of spill response equipment, and the procedures to report and respond to a spill incident. Records of site orientations are maintained.

For key NTPC employees responsible to coordinate a response to spill events, NTPC provides an SCP awareness course. In addition to the information provided during the site orientation, spill responders are given a detailed review of this SCP; introduced to step-by-step methods to identify, assess, and respond to spill situations; participate in a review of hazardous materials located on- site and the associated risks; learn how to use absorbent and other spill response equipment; and learn how to properly dispose of contaminated spill response equipment. A mock spill exercise

Page 48 Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

may be performed to familiarize on-site spill responders with the equipment available and the steps to take during typical spills situations that may occur at the Facility.

All contractors are required to have basic first aid and WHMIS training before being allowed to work at the Facility. All Facility employees and supervisors are also required to have WHMIS and first aid training. Persons involved in the handling and shipping of hazardous materials are required to be trained in the Transportation of Dangerous Goods Regulation (TDG) requirements and must have a valid TDG certificate.

An up-to-date training matrix is kept by the NTPC Training Coordinator and contains records of all environmental, health and safety training completed by employees.

8.1 SPILL CONTINGENCY PLAN TRAINING PROGRAM

The NTPC SCP Training Program is mandatory for all employees. It includes a 55-slide PowerPoint presentation and reviews the following details pertaining to the NTPC spill response processes and this SCP:

• scope; • person in charge; • community information; • facility site specifics; • layout; • sensitive environmental receptors; • spill control; • on site product storage; • power transformers; • bulk petroleum product storage; • product information; • spill kits and spill response equipment; and • heavy equipment. • health and safety; • spill response procedures; • spill reporting; • general cleanup methods; and • spill volume calculation procedures.

Page 49 Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

9 PUBLIC RELATIONS

9.1 GENERAL POLICY ON PUBLIC RELATIONS

If questioned by the public or the media about a spill, refer them to Director, Hydro Operations.

Environmental incidents such as spills often attract local interest and media attention. Employees should not make any statements on behalf of the Corporation to the media or to the public. It is the responsibility of the Regional Director and/or the NTPC Manager, Communications to address the media and thereby the public.

Respond fully to any request from local authorities or emergency workers that will help to control the spill and its damage; however refer all other requests for information to the Director, Hydro Operations. This may include questions from reporters, environmental agencies, or people and property owners affected by a spill. When probing questions are asked, it is important that the response is polite and professional; for example:

“I’m sorry; I don’t have the authority to answer that question. Please contact my Regional Director. His/her phone number is ______.”

Employees should avoid guessing at an answer or making promises that are out of their control, as this can cause problems later for both the employee and the Corporation. No speculation should be made with regard to who is at fault, why the spill occurred, spill volume, when cleanup will be completed, or any other issue. It is the responsibility of the company representative at the site to keep the Director, Hydro Operations informed so that media questions directed to the Corporation can be answered.

FUEL SPILL CALCULATION PROCEDURES

OPERATIONS & MAINTENANCE Standard # 301.21 Date Issued 11/13/07 Diesel Fuel, General, Section 30l Page 1 of 2 Prepared by: Joe Staszuk SUBJECT: FUEL SPILL CALCULATIONS Approved by

FUEL SPILL RESPONSE PROCEDURE

In the even of a fuel spill the following steps must be taken:

1. Assess hazards 2. Shut off source of spill 3. Contain spill 4. Calculate amount of fuel spilled 5. Report Spill 6. Spill cleanup and disposal 7. Debriefing

FUEL SPILL CALCULATIONS

Once the source of the spill is shut off and the initial spill containment is underway it is essential to determine the exact amount of fuel spilled. To do so, the following information must be gathered:

1. Gauge the tank with the fuel spill and record the reading 2. Record the fuel temperature 3. Record the generator kWh readings for each engine in the plant 4. Obtain a copy of the last Month End Thermal Generation Report (Month End Report)

FUEL DIFFERENCE CALCULATION

1. Record last month’s fuel storage volume (Month End Report pages 4-6, line 7)  e.g., 33,737 L

2. Add any fuel received between last month end and the fuel spill  e.g., no fuel was received (0 L)

3. Conduct a tank dip and record the depth of fuel  e.g., 98 cm

4. From the tank dip chart for that specific tank determine the volume of fuel in the tank  e.g., 22,708 L

5. Using the recorded fuel temperature obtain the multiplier from the Temperature Compensation Chart  e.g., -280C = 1.0383

6. Obtain the amount of temperature compensated fuel in storage  e.g., (22,708 L x 1.0383) = 23,578 L

7. Subtract temperature compensated fuel volume from last month end volume to calculate Fuel Used Since Last Month End  e.g., (33,737 L – 23,578 L) = 10,159 L  This means that the fuel used and spilled since last month end totals 10,159 L OPERATIONS & MAINTENANCE Standard # 301.21 Date Issued 11/13/07 Diesel Fuel, General, Section 30l Page 2 of 2 Prepared by: Joe Staszuk SUBJECT: FUEL SPILL CALCULATIONS Approved by

FUEL USED IN GENERATION (Table 1 below corresponds with the following steps)

1. Take the present kWh meter readings for each generator from the kWh meter in the generator switchgear  e.g.,G1 (17,748,000 kWh), G2 (10,110 kWh), G3 (10,820 kWh)

2. Record the previous meter readings from each generator from Month End Report  e.g., G1 (17,735,465 kWh), G2 (10,087 kWh), G3 (10,809 kWh)

3. Subtract the difference between present and last month end readings for each generator  e.g., G1 (12,535 kWh), G2 (23 kWh), G3 (11 kWh)

4. Obtain meter multipliers from the meters or the Month End Report  e.g., G1(x 1), G2(x 600), and G3 (x 600).

5. Obtain actual kWh generated by each unit in the plant using the multiplier  e.g., G1 (12,535), G2 (13,800), G3 (6,600)

6. Add the actual generation for all units to get the total generation from end of last month to present  e.g., 32,935 kWh

7. Obtain the fuel efficiency from the Month End Report  e.g., 3.47 kWh/L

8. Calculate fuel used to generate 32,935 kWh by applying fuel efficiency to total generation  e.g., (32,935 kWh / 3.47 kWh/L) = 9,491 L

9. Calculate the Actual Spill Volume (fuel used since last month end minus fuel used to generate during this period)  e.g., (10,159 L – 9,491 L) = 668 L

SPILL CONTAINMENT METHODS

• Containment of Spills on Land • Containment of Spills on Water • Containment of Spills on and Under Ice • Containment of Spills on Snow

Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

Specific Spill Containment Methods For Land, Water, Ice And Snow The following section describes various methods which may be employed to contain a spill to land, water, ice or snow.

Containment of Spills on Land Spills on land include spills on rock, gravel, soil and/or vegetation. It is important to note that soil is a natural sorbent, thus spills on soil are generally less serious then spills on water as contaminated soil can be more easily recovered. Generally spills on land occur during the late spring, summer or fall when snow cover is at a minimum. It is important that all measures be undertaken to avoid spills reaching open water bodies.

Dykes Dykes can be created using soil surrounding a spill on land. These dykes are constructed around the perimeter or down slope of the spilled fuel. A dyke needs to be built up to a size that will ensure the containment of the maximum quantity of fuel that may reach it. A plastic tarp can be placed on and at the base of the dyke such that fuel can pool up and the subsequently be removed with sorbent materials or by pump into barrels or bags. If the spill is migrating very slowly a dyke may not be necessary and sorbents can be used to soak up fuels before they migrate away from the source of the spill.

Trenches Trenches can be dug out to contain spills as long as the top layer of soil is thawed. Backhoes, loaders, shovels, or pick axes can be used depending on the size of the trench required. It is recommended that the trench be dug to the bedrock or permafrost, which will then provide containment layer for the spilled fuel. Fuel can then be recovered using a pump or sorbent materials. Care must be given when working in or near trenches as fumes can build up, causing fire and respiratory hazards. Ensure proper PPE is worn and ignition sources are removed from the area.

If water is present in the excavated trenches, it should be assumed that groundwater contamination may result and eventually be discharged into surface waters. A waterproof liner should be placed on the bottom and sides of the trench.

Shallow trenches placed downslope of the spill will be effective in trapping fuel travelling both on the surface and below the surface (Figure E-1). Sorbent pads, socks, and booms should be placed in the trench to collect spilled product.

Figure E-1: Trench

Impermeable Ground

Dams Dams constructed across ditches can be used to contain a spill and stop its flow. A dam may be built with earth, wood, sandbags, and/or snow. The dam should be lined with plastic sheeting to make it impermeable to the spilled product. In freezing conditions water may be sprayed on a dam to form ice, thereby making the dam impermeable.

Care should be taken to ensure that a dam is large enough to contain the entire spill; insufficient capacity may result in overtopping failure.

For ditches with flowing water or for small streams, it may be necessary to allow water flow to continue while retaining the lighter-than-water liquids (i.e.: hydrocarbons). This can be achieved by building water bypass dams: an earth dam is built stopping the flow of water and oil in the ditch; a pipe is then installed below the water level and passing through the dam. This allows the water to continue flowing while the dam retains the lighter-than-water products (Figure E-2).

Figure E-2: Water Bypass Dam

Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

Containment of Spills to Water Spills on water such as rivers, streams or lakes are the most serious types of spills as they can negatively impact water quality and aquatic life. All measures need to be undertaken to contain spills on open water.

Booms Booms are commonly used to contain a spill of floating liquid or debris, to deflect or divert material to a defined area so that it may be recovered, and to protect sensitive areas from contamination (Figure E-3). Booms are designed to float and have absorbent materials built into them to absorb fuels at the edge of the boom.

Boom deployment is important, as the angle of the boom in relation to the speed of the water affects how well the oil may be contained. The faster the stream, the more angled the boom must be (Figure E-4).

Several booms arranged in parallel may be necessary to contain all of the product. These should be spaced to allow product, which may escape the first boom, to float to the surface and be contained by the next boom. In addition, the use of several booms permits one boom to be removed at a time for cleaning.

Booms may be either commercially made or homemade. Commercially made booms are designed to float and keep product from escaping under the boom. Homemade booms may be constructed from logs, railroad ties, power poles, trees, lumber, inflated fire hose, or Styrofoam. These may be used to deflect floating material to shore or to keep floating material within a contained area. Individual sections are connected together by rope, chain, or wire. A seal around the joints to prevent leakage can be made by wrapping with plastic sheets or burlap.

Wooden or other floating booms can be used to contain the spilled fluid itself or the sorbent containing the product. They can also be used upstream of sorbent booms to improve the efficiency and longevity of the sorbent material.

Fuel contained within the boom will need to be recovered using sorbent materials or pumps and placed into barrels or bags for disposal.

Figure E-4: Boom Deployment

Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

Weirs Weirs can be used to contain spills in streams, ditches, at culvert entrances and to prevent further migration downstream.

Materials commonly used such as plywood, lumber, and sheet metal may be placed into and across the width of the stream/ditch/culvert such that water can still flow under the weir. Spilled fuel will float on the water surface and be contained at the foot of the weir (Figure E-5). It can then be removed using sorbents, booms or pumps and placed into barrels or plastic bags.

Figure E-5: Weirs

Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

Barriers In some situations, barriers made of netting or fence material can be installed across a stream, and sorbent materials placed at the base to absorb the spilled product. Sorbents will need to be replaced as soon as they are saturated. Water will be allowed to flow through. This is very similar to the weir option discussed above.

Note that in some cases, it may be appropriate to burn fuel or to let volatile fuels such as gasoline evaporate after containment on the water surface. This should only be undertaken in consultation with and after approval from the INAC or lead agency inspector.

Containment of Spills On and Under Ice Spills on ice are generally the easiest spills to contain due to the predominantly impermeable nature of the ice. For small spills, sorbent materials are used to soak up spilled fuel. Remaining contaminated ice/slush can be scraped and shovelled into a plastic bag or barrel. However, all possible attempts should be made to prevent spills from entering ice covered waters as no easy method exists for containment and recovery of spills if they seep under ice.

Dykes Dykes can be used to contain fuel spills on ice. By collecting surrounding snow, compacting it and mounding it to form a dyke down slope of the spill, a barrier is created thus helping to contain the spill. If the quantity of spill is fairly large, a plastic tarp can be placed over the dyke such that the spill pools at the base of the dyke. The collected fuel can then be pumped into barrels or collected with sorbent materials.

Trenches For significant spills on ice, trenches can be cut into the ice surrounding and/or down slope of the spill such that fuel is allowed to pool in the trench. It can then be removed via pump into barrels, collected with sorbent materials, or mixed with snow and shovelled into barrels or bags.

Snow Fence and Sorbent Barrier Snow fence and sorbent barriers may be used in streams (less than 1 m deep) with soft beds into which stakes can be driven. This method is limited to summer conditions. A snow fence barrier is installed to span the width of the stream, anchored at both ends, and stakes are driven into the stream bottom at 1 to 2 m intervals along the fence. Commercial sorbents are placed on the upstream side of the fence and are held against it by the current. Sorbents will float against the upstream side of the barrier, but must be replaced before they become soaked with product and sink. The barrier should be angled against the current for shore side collection. Multiple snow fence barriers can provide backup against potential losses from upstream barriers. Net or chicken wire barriers can be constructed in the same way, and are more practical for stronger currents, as water can flow through them more easily (Figure E-6).

Figure E-6: Barrier and Sorbent

Burning Burning should only be considered if other approaches are not feasible, and is only to be undertaken with the permission of the GNWT ENR Inspector.

Ice Slotting For spills under the ice in rivers or streams when current speeds are slow (i.e., less than 0.5 m/s), ice slotting may be used. A trench is cut into the ice using a chain saw or trenching machine at an angle to the current, to deflect and concentrate product that passes through the area (Figure E-7, E-8). Because of thick ice encountered during the winter, cutting and removal of ice blocks is often difficult. Loaders or backhoes may be needed to lift blocks out of the slot, or to push blocks down. Product that accumulates in the ice slot may be pumped out, adsorbed, or burned in place.

Vertical Barriers If the spill goes under the ice in deep, slow moving water, vertical barriers such as plywood may be used to deflect product (Figure E-9). The ice must be strong enough to support the necessary personnel and equipment. Vertical barriers are put in place by cutting trenches in the ice at an angle to current flow, inserting the plywood barriers, and allowing them to freeze in place. The location of the spilled product may be monitored by drilling observation holes with an ice-auger.

Figure E-9: Vertical Barriers

Containment of Spills on Snow Snow is a natural sorbent, thus as with spills on soil, spilled fuel can be more easily recovered. Generally, small spills on snow can be easily cleaned up by raking and shovelling the contaminated snow into plastic bags or empty barrels, and storing these at an approved location.

Dykes Dykes can be used to contain fuel spills on snow. By compacting snow down slope from the spill, and mounding it to form a dyke, a barrier or berm is created thus helping to contain the spill. If the quantity of the spill is fairly large, a plastic tarp can be placed over the dyke such that the spill pools at the base of the dyke. The collected fuel/snow mixture can then be shovelled into barrels or bags, or collected with sorbent materials.

SPILL KITS

Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

9.2 SPILL KITS AND EQUIPMENT

NTPC employs two types of sorbent for spill response.

• Universal Sorbents: These sorbents pick up most liquids including fuel, oil, glycol, and water. They are used for general spill cleanup on dry land and will sink if placed on water, as they adsorb the water (hydrophilic). For this reason universal sorbents are not to be used on hydrocarbon spills into water. • Oil Only Sorbents: These sorbents only pick up hydrocarbons, such as fuel or lube oil. These sorbents float, as they do not pick up water (hydrophobic), and are to be used for any hydrocarbon spill into water. Higher quality sorbents will wick up, contain, and retain spilled product much faster and more effectively than low quality sorbent, due to a finer weave of material. Low quality sorbent pads are used around the Facility to clean up drips while higher quality sorbents, found in the spill kits, are used for larger spills.

All plants are equipped with universal sorbent pads for day to day use and the cleanup of spills. For any large or significant spills, spill kits are available for containment and cleanup. Spill kits can be stored both indoors and outdoors and are generally contained in one of the following (see Figure F-1):

• Overpack Drum: A yellow plastic drum designed to contain a leaking drum or used/unused spill material. • Steel Salvage Drum: A 205 L steel drum with removable top used to contain used/unused spill material, impacted soil or snow, etc. • Spill Kit Locker: A plastic bin used for spill kit material storage.

Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

Figure F-1: Typical Spill Kits

Spill kits generally contain the following spill response materials:

Sorbent Booms: When a spill occurs into water, floating booms are placed around the spill perimeter to provide containment. Typically a 5 or 8 inch diameter plastic net tube filled with sorbent material, booms prevent the spill from spreading and/or moving downstream to contaminate other areas (see Figure F-2).

Figure F-2: Sorbent Booms

Booms can be clipped together for extra length. The ends should be clipped together so that they overlap, leaving no space at the joint. This ensures that no spilled product leaks out past the boom, and the boom effectively contains and adsorbs the spilled product (see Figure F-3).

• Sorbent Socks: Socks are identical to booms in construction; however, they do not clip together. They are generally used for small scale, localized spills. • Sorbent Pads: Individual pads used on drips or leaks.

Northwest Territories Power Corporation Spill Contingency Plan Snare Hydroelectric Facility

• Sorbent Rolls: A continuous roll of sorbent pads. • Printed Disposal Bags: Soiled absorbent material is put into printed disposal bags which are then tied off for disposal. • Instruction Book: The spill kit instruction book provides information regarding spill kit equipment. • Personal Protective Equipment: Used to augment Facility equipment and supplies. Includes rubber gloves, safety goggles, and protective coveralls.

Personal protective equipment Respiratory protection : Concentration in air determines protection needed. Use respiratory protection unless adequate local exhaust ventilation is provided or exposure assessment demonstrates that exposures are within recommended exposure guidelines. Respirator selection must be based on known or anticipated exposure levels, the hazards of the product and the safe working limits of the selected respirator.

Filter type : organic vapour cartridge or canister may be permissible un- der certain circumstances where airborne concentrations are expected to exceed exposure limits. Protection provided by air-purifying respirators is limited. Use a positive-pressure, air-supplied respirator if there is any potential for uncontrolled release, exposure levels are unknown, or any other circum- stances where air-purifying respirators may not provide ade- quate protection.

Hand protection Material : neoprene, nitrile, polyvinyl alcohol (PVA), Viton(R). Consult your PPE provider for breakthrough times and the specific glove that is best for you based on your use patterns. It should be realized that eventually any material regardless of their imperviousness, will get permeated by chemicals. Therefore, protective gloves should be regularly checked for wear and tear. At the first signs of hardening and cracks, they should be changed.

INHALATION Remove from further exposure. For those providing assistance, avoid exposure to yourself or others. Use adequate respiratory protection. If respiratory irritation, dizziness, nausea, or unconsciousness occurs, seek immediate medical assistance. If breathing has stopped, assist ventilation with a mechanical device or use mouth-to-mouth resuscitation.

SKIN CONTACT Wash contact areas with soap and water. Remove contaminated clothing. Launder contaminated clothing before reuse. If product is injected into or under the skin, or into any part of the body, regardless of the appearance of the wound or its size, the individual should be evaluated immediately by a physician as a surgical emergency. Even though initial symptoms from high pressure injection may be minimal or absent, early surgical treatment within the first few hours may significantly reduce the ultimate extent of injury.

EYE CONTACT Flush thoroughly with water. If irritation occurs, get medical assistance.

INGESTION Seek immediate medical attention. Do not induce vomiting.

NOTE TO PHYSICIAN If ingested, material may be aspirated into the lungs and cause chemical pneumonitis. Treat appropriately. This material, or a component, may be associated with cardiac sensitization following very high exposures (well above occupational exposure limits) or with concurrent exposure to high stress levels or heart-stimulating substances like epinephrine. Administration of such substances should be avoided.

SECTION 5 FIRE-FIGHTING MEASURES

EXTINGUISHING MEDIA Appropriate Extinguishing Media: Use water fog, foam, dry chemical or carbon dioxide (CO2) to extinguish flames.

Inappropriate Extinguishing Media: Straight streams of water

FIRE FIGHTING Fire Fighting Instructions: Evacuate area. If a leak or spill has not ignited, use water spray to disperse the vapours and to protect personnel attempting to stop a leak. Prevent run-off from fire control or dilution from entering streams, sewers or drinking water supply. Fire-fighters should use standard protective equipment and in enclosed spaces, self-contained breathing apparatus (SCBA). Use water spray to cool fire exposed surfaces and to protect personnel.

Unusual Fire Hazards: Extremely Flammable. Vapour is flammable and heavier than air. Vapour may travel across the ground and reach remote ignition sources, causing a flashback fire danger. Hazardous material. Firefighters should consider protective equipment indicated in Section 8.

Hazardous Combustion Products: Aldehydes, Incomplete combustion products, Oxides of carbon, Smoke,

Product Name: GASOLINE UNLEADED WITH ETHANOL (GASOHOL) Revision Date: 02 Oct 2018 Page 5 of 15 ______Fume, Sulphur oxides

FLAMMABILITY PROPERTIES Flash Point [Method]: -40°C (-40°F) [ASTM D-92] Flammable Limits (Approximate volume % in air): LEL: 1.5 UEL: 7.6 Autoignition Temperature: N/D

SECTION 6 ACCIDENTAL RELEASE MEASURES

NOTIFICATION PROCEDURES In the event of a spill or accidental release, notify relevant authorities in accordance with all applicable regulations.

PROTECTIVE MEASURES Avoid contact with spilled material. Warn or evacuate occupants in surrounding and downwind areas if required, due to toxicity or flammability of the material. See Section 5 for fire fighting information. See the Hazard Identification Section for Significant Hazards. See Section 4 for First Aid Advice. See Section 8 for advice on the minimum requirements for personal protective equipment. Additional protective measures may be necessary, depending on the specific circumstances and/or the expert judgment of the emergency responders.

For emergency responders: Respiratory protection: half-face or full-face respirator with filter(s) for organic vapor and, when applicable, H2S, or Self Contained Breathing Apparatus (SCBA) can be used depending on the size of spill and potential level of exposure. If the exposure cannot be completely characterized or an oxygen deficient atmosphere is possible or anticipated, SCBA is recommended. Work gloves that are resistant to aromatic hydrocarbons are recommended. Note: gloves made of polyvinyl acetate (PVA) are not water- resistant and are not suitable for emergency use. Chemical goggles are recommended if splashes or contact with eyes is possible. Small spills: normal antistatic work clothes are usually adequate. Large spills: full body suit of chemical resistant, antistatic material is recommended.

SPILL MANAGEMENT Land Spill: Eliminate all ignition sources (no smoking, flares, sparks or flames in immediate area). Stop leak if you can do so without risk. All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Prevent entry into waterways, sewer, basements or confined areas. A vapour-suppressing foam may be used to reduce vapour. Use clean non-sparking tools to collect absorbed material. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Large Spills: Water spray may reduce vapour, but may not prevent ignition in enclosed spaces.

Water Spill: Eliminate all ignition sources (no smoking, flares, sparks or flames in immediate area). Stop leak if you can do so without risk. Do not confine in area of spill. Advise occupants and shipping in downwind areas of fire and explosion hazard and warn them to stay clear. Allow liquid to evaporate from the surface. Seek the advice of a specialist before using dispersants.

Water spill and land spill recommendations are based on the most likely spill scenario for this material; however, geographic conditions, wind, temperature, (and in the case of a water spill) wave and current direction and speed may greatly influence the appropriate action to be taken. For this reason, local experts should be consulted. Note: Local regulations may prescribe or limit action to be taken.

ENVIRONMENTAL PRECAUTIONS Large Spills: Dyke far ahead of liquid spill for later recovery and disposal. Prevent entry into waterways,

Product Name: GASOLINE UNLEADED WITH ETHANOL (GASOHOL) Revision Date: 02 Oct 2018 Page 6 of 15 ______sewers, basements or confined areas.

SECTION 7 HANDLING AND STORAGE

HANDLING Avoid breathing mists or vapour. Avoid all personal contact. Prevent exposure to ignition sources, for example use non-sparking tools and explosion-proof equipment. Potentially toxic/irritating fumes/vapour may be evolved from heated or agitated material. Do not siphon by mouth. Use only with adequate ventilation. Do not use as a cleaning solvent or other non-motor fuel uses. For use as a motor fuel only. It is dangerous and/or unlawful to put petrol into unapproved containers. Do not fill container while it is in or on a vehicle. Static electricity may ignite vapour and cause fire. Place container on ground when filling and keep nozzle in contact with container. Do not use electronic devices (including but not limited to cellular phones, computers, calculators, pagers or other electronic devices etc) in or around any fuelling operation or storage area unless the devices are certified intrinsically safe by an approved national testing agency and to the safety standards required by national and/or local laws and regulations. Prevent small spills and leakage to avoid slip hazard. Material can accumulate static charges which may cause an electrical spark (ignition source). Use proper bonding and/or ground procedures. However, bonding and grounds may not eliminate the hazard from static accumulation. Consult local applicable standards for guidance. Additional references include American Petroleum Institute 2003 (Protection Against Ignitions Arising out of Static, Lightning and Stray Currents) or National Fire Protection Agency 77 (Recommended Practice on Static Electricity) or CENELEC CLC/TR 50404 (Electrostatics - Code of practice for the avoidance of hazards due to static electricity).

Static Accumulator: This material is a static accumulator. A liquid is typically considered a nonconductive, static accumulator if its conductivity is below 100 pS/m (100x10E-12 Siemens per meter) and is considered a semiconductive, static accumulator if its conductivity is below 10,000 pS/m. Whether a liquid is nonconductive or semiconductive, the precautions are the same. A number of factors, for example liquid temperature, presence of contaminants, anti-static additives and filtration can greatly influence the conductivity of a liquid.

STORAGE Ample fire water supply should be available. A fixed sprinkler/deluge system is recommended. The type of container used to store the material may affect static accumulation and dissipation. Keep container closed. Handle containers with care. Open slowly in order to control possible pressure release. Store in a cool, well- ventilated area. Outside or detached storage preferred. Storage containers should be earthed and bonded. Fixed storage containers, transfer containers and associated equipment should be grounded and bonded to prevent accumulation of static charge.

TOXICITY FOR SUBSTANCES

NAME ACUTE TOXICITY ETHYL BENZENE Inhalation Lethality: 4 hour(s) LC50 17.8 mg/l (Vapour) (Rat); Oral Lethality: LD 50 3.5 g/kg (Rat) Naphthalene Inhalation Lethality: 4 hour(s) LC50 > 0.4 mg/l (Max attainable vapor conc.) (Rat); Oral Lethality: LD 50 533 mg/kg (Mouse)

OTHER INFORMATION For the product itself:

Laboratory animal studies have shown that prolonged and repeated inhalation exposure to light hydrocarbon vapours in the same boiling range as this product can produce adverse kidney effects in male rats. However, these effects were not observed in similar studies with female rats, male and female mice, or in limited studies with other animal species. Additionally, in a number of human studies, there was no clinical evidence of such effects at normal occupational levels. In 1991, The U.S. EPA determined that the male rat kidney is not useful for assessing human risk. Vapour concentrations above recommended exposure levels are irritating to the eyes and the respiratory tract, may cause headaches and dizziness, are anaesthetic and may have other central nervous system effects. Small amounts of liquid aspirated into the lungs during ingestion or from vomiting may cause chemical pneumonitis or pulmonary edema. Exposure to this material, or one of its components, in situations where there is the potential for high levels, such as in confined spaces or with abuse, may result in abnormal heart rhythm (arrhythmia). High-level exposure to hydrocarbons (above occupational exposure limits) may initiate arrhythmia in a worker that is undergoing stress or is taking a heart-stimulating substance such as epinephrine, a nasal decongestant, or an asthma or cardiovascular drug. Contains: BENZENE: Caused cancer (acute myeloid leukemia and myelodysplastic syndrome), damage to the blood-producing system, and serious blood disorders in human studies. Caused genetic effects and effects on the immune system in laboratory animal and some human studies. Caused toxicity to the fetus and cancer in laboratory animal studies. CUMENE: Repeated inhalation exposure of cumene vapour produced damage in the kidney of male rats only. These effects are believed to be species specific and are not relevant to humans. ETHANOL: Prolonged or repeated exposure to high concentrations of ethanol vapour or overexposure by ingestion may produce adverse effects to brain, kidney, liver, and reproductive organs, birth defects in offspring, and developmental toxicity in offspring. GASOLINE UNLEADED: Carcinogenic in animal tests. Chronic inhalation studies resulted in liver tumours in female mice and kidney tumours in male rats. Neither result considered significant for human health risk assessment by the United States EPA and others. Did not cause mutations in-vitro or in-vivo. Negative in inhalation developmental studies and reproductive tox studies. Inhalation of high concentrations in animals resulted in reversible central nervous system depression, but no persistent toxic effect on the nervous system. Non-sensitizing in test animals. Caused nerve damage in humans from abusive use (sniffing). NAPHTHALENE: Exposure to high concentrations of naphthalene may cause destruction of red blood cells, anemia, and cataracts. Naphthalene caused cancer in laboratory animal studies, but the relevance of these findings to humans is uncertain. N-HEXANE: Prolonged and/or repeated exposures to n-Hexane can cause progressive and potentially irreversible damage to the peripheral nervous system (e.g. fingers, feet, arms, legs, etc.). Simultaneous exposure to Methyl Ethyl Ketone (MEK) or Methyl Isobutyl Ketone (MIBK) and n-Hexane can potentiate the risk of adverse effects from n-Hexane on the peripheral nervous system. n-Hexane has been shown to cause testicular damage at high doses in male rats. The relevance of this effect for humans is unknown. TOLUENE : Concentrated, prolonged or deliberate inhalation may cause brain and nervous system damage. Prolonged and repeated exposure of pregnant animals (> 1500 ppm)

Product Name: GASOLINE UNLEADED WITH ETHANOL (GASOHOL) Revision Date: 02 Oct 2018 Page 11 of 15 ______have been reported to cause adverse fetal developmental effects. ETHYLBENZENE: Caused cancer in laboratory animal studies. The relevance of these findings to humans is uncertain.

SECTION 5 FIRE-FIGHTING MEASURES

EXTINGUISHING MEDIA Appropriate Extinguishing Media: Use water fog, foam, dry chemical or carbon dioxide (CO2) to extinguish flames.

Inappropriate Extinguishing Media: Straight streams of water

FIRE FIGHTING Fire Fighting Instructions: Evacuate area. Prevent run-off from fire control or dilution from entering streams, sewers or drinking water supply. Fire-fighters should use standard protective equipment and in enclosed spaces, self-contained breathing apparatus (SCBA). Use water spray to cool fire exposed surfaces and to protect personnel.

Unusual Fire Hazards: Combustible. Vapour is flammable and heavier than air. Vapour may travel across the ground and reach remote ignition sources, causing a flashback fire danger. Hazardous material. Firefighters should consider protective equipment indicated in Section 8.

Hazardous Combustion Products: Aldehydes, Incomplete combustion products, Oxides of carbon, Smoke, Fume, Sulphur oxides

FLAMMABILITY PROPERTIES Flash Point [Method]: 38°C (100°F) [ASTM D-93] Flammable Limits (Approximate volume % in air): LEL: 0.7 UEL: 5.0 Autoignition Temperature: N/D

SECTION 6 ACCIDENTAL RELEASE MEASURES

NOTIFICATION PROCEDURES In the event of a spill or accidental release, notify relevant authorities in accordance with all applicable regulations.

PROTECTIVE MEASURES Avoid contact with spilled material. Warn or evacuate occupants in surrounding and downwind areas if required, due to toxicity or flammability of the material. See Section 5 for fire fighting information. See the Hazard Identification Section for Significant Hazards. See Section 4 for First Aid Advice. See Section 8 for advice on the minimum requirements for personal protective equipment. Additional protective measures may be necessary, depending on the specific circumstances and/or the expert judgment of the emergency responders.

For emergency responders: Respiratory protection: half-face or full-face respirator with filter(s) for organic vapor and, when applicable, H2S, or Self Contained Breathing Apparatus (SCBA) can be used depending on the size of spill and potential level of exposure. If the exposure cannot be completely characterized or an oxygen deficient atmosphere is possible or anticipated, SCBA is recommended. Work gloves that are resistant to aromatic hydrocarbons are recommended. Note: gloves made of polyvinyl acetate (PVA) are not water- resistant and are not suitable for emergency use. Chemical goggles are recommended if splashes or contact with eyes is possible. Small spills: normal antistatic work clothes are usually adequate. Large spills: full body suit of chemical resistant, antistatic material is recommended.

Product Name: KEROSENE TYPE AVIATION TURBINE FUEL Revision Date: 25 May 2017 Page 5 of 13 ______SPILL MANAGEMENT Land Spill: Eliminate all ignition sources (no smoking, flares, sparks or flames in immediate area). Stop leak if you can do so without risk. All equipment used when handling the product must be grounded. Do not touch or walk through spilled material. Prevent entry into waterways, sewer, basements or confined areas. A vapour-suppressing foam may be used to reduce vapour. Use clean non-sparking tools to collect absorbed material. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. Large Spills: Water spray may reduce vapour, but may not prevent ignition in enclosed spaces.

Water Spill: Stop leak if you can do so without risk. Eliminate sources of ignition. Warn other shipping. If the Flash Point exceeds the Ambient Temperature by 10 deg C or more, use containment booms and remove from the surface by skimming or with suitable absorbents when conditions permit. If the Flash Point does not exceed the Ambient Air Temperature by at least 10C, use booms as a barrier to protect shorelines and allow material to evaporate. Seek the advice of a specialist before using dispersants.

Water spill and land spill recommendations are based on the most likely spill scenario for this material; however, geographic conditions, wind, temperature, (and in the case of a water spill) wave and current direction and speed may greatly influence the appropriate action to be taken. For this reason, local experts should be consulted. Note: Local regulations may prescribe or limit action to be taken.

ENVIRONMENTAL PRECAUTIONS Large Spills: Dyke far ahead of liquid spill for later recovery and disposal. Prevent entry into waterways, sewers, basements or confined areas.

SECTION 7 HANDLING AND STORAGE

HANDLING Avoid all personal contact. Do not siphon by mouth. Do not use as a cleaning solvent or other non-motor fuel uses. For use as a motor fuel only. It is dangerous and/or unlawful to put petrol into unapproved containers. Do not fill container while it is in or on a vehicle. Static electricity may ignite vapour and cause fire. Place container on ground when filling and keep nozzle in contact with container. Do not use electronic devices (including but not limited to cellular phones, computers, calculators, pagers or other electronic devices etc) in or around any fuelling operation or storage area unless the devices are certified intrinsically safe by an approved national testing agency and to the safety standards required by national and/or local laws and regulations. Prevent small spills and leakage to avoid slip hazard. Material can accumulate static charges which may cause an electrical spark (ignition source). Use proper bonding and/or ground procedures. However, bonding and grounds may not eliminate the hazard from static accumulation. Consult local applicable standards for guidance. Additional references include American Petroleum Institute 2003 (Protection Against Ignitions Arising out of Static, Lightning and Stray Currents) or National Fire Protection Agency 77 (Recommended Practice on Static Electricity) or CENELEC CLC/TR 50404 (Electrostatics - Code of practice for the avoidance of hazards due to static electricity).

Static Accumulator: This material is a static accumulator. A liquid is typically considered a nonconductive, static accumulator if its conductivity is below 100 pS/m (100x10E-12 Siemens per meter) and is considered a semiconductive, static accumulator if its conductivity is below 10,000 pS/m. Whether a liquid is nonconductive or semiconductive, the precautions are the same. A number of factors, for example liquid temperature, presence of contaminants, anti-static additives and filtration can greatly influence the conductivity of a liquid.

STORAGE The type of container used to store the material may affect static accumulation and dissipation. Keep

Product Name: KEROSENE TYPE AVIATION TURBINE FUEL Revision Date: 25 May 2017 Page 6 of 13 ______container closed. Handle containers with care. Open slowly in order to control possible pressure release. Store in a cool, well-ventilated area. Storage containers should be earthed and bonded. Fixed storage containers, transfer containers and associated equipment should be grounded and bonded to prevent accumulation of static charge.

OTHER INFORMATION For the product itself:

Vapour/aerosol concentrations above recommended exposure levels are irritating to the eyes and respiratory tract, may cause headaches, dizziness, anaesthesia, drowsiness, unconsciousness and other central nervous system effects including death. Small amounts of liquid aspirated into the lungs during ingestion or from vomiting may cause chemical pneumonitis or pulmonary edema. DIETHYLENE GLYCOL MONOMETHYL ETHER: Oral maternal exposure of animals resulted in teratogenicity. Dermal maternal exposure of animals resulted in slight toxicity to the fetus. Jet fuel: Some jet fuels have potential in mice to suppress indicators of immune system functionality. The relevance of these effects to humans is uncertain.

Contains: KEROSENE: Carcinogenic in animal tests. Lifetime skin painting tests produced tumours, but the mechanism is due to repeated cycles of skin damage and restorative hyperplasia. This mechanism is considered unlikely in humans where such prolonged skin irritation would not be tolerated. Did not cause mutations in-vitro. Inhalation of vapours did not result in reproductive or developmental effects in laboratory animals. Inhalation of high concentrations in animals resulted in respiratory tract irritation, lung changes and some reduction in lung function. Non-sensitizing in animal tests. NAPHTHALENE: Exposure to high concentrations of naphthalene may cause destruction of red blood cells, anemia, and cataracts. Naphthalene caused cancer in laboratory animal studies, but the relevance of these findings to humans is uncertain.

SECTION 4 FIRST-AID MEASURES

INHALATION Immediately remove from further exposure. Get immediate medical assistance. For those providing assistance, avoid exposure to yourself or others. Use adequate respiratory protection. Give supplemental oxygen, if available. If breathing has stopped, assist ventilation with a mechanical device.

SKIN CONTACT If product is injected into or under the skin, or into any part of the body, regardless of the appearance of the wound or its size, the individual should be evaluated immediately by a physician as a surgical emergency. Even though initial symptoms from high pressure injection may be minimal or absent, early surgical treatment within the first few hours may significantly reduce the ultimate extent of injury. If frostbite occurs, immerse involved area in water at body temperature. Keep immersed for 20 to 40 minutes. Seek medical assistance.

EYE CONTACT Flush thoroughly with water for at least 15 minutes. Get medical assistance.

INGESTION Not Applicable

NOTE TO PHYSICIAN This material, or a component, may be associated with cardiac sensitization following very high exposures (well above occupational exposure limits) or with concurrent exposure to high stress levels or heart-stimulating substances like epinephrine. Administration of such substances should be avoided.

SECTION 5 FIRE-FIGHTING MEASURES

EXTINGUISHING MEDIA Appropriate Extinguishing Media: Use water fog, dry chemical or carbon dioxide (CO2) to extinguish flames.

Inappropriate Extinguishing Media: Straight streams of water

FIRE FIGHTING Fire Fighting Instructions: Allow the fire to burn under controlled conditions. Stop leak if you can do so without risk. Evacuate area. If a leak or spill has not ignited, use water spray to disperse the vapours and to protect personnel attempting to stop a leak. Prevent run-off from fire control or dilution from entering streams, sewers or drinking water supply. Fire-fighters should use standard protective equipment and in enclosed spaces, self-contained breathing apparatus (SCBA). Use water spray to cool fire exposed surfaces and to protect personnel.

Unusual Fire Hazards: Flammable Gas. Vapour is flammable and heavier than air. Vapour may travel across the ground and reach remote ignition sources, causing a flashback fire danger. Hazardous material. Firefighters should consider protective equipment indicated in Section 8.

Product Name: COMMERCIAL PROPANE (NON ODORIZED) Revision Date: 22 Dec 2017 Page 4 of 11 ______Hazardous Combustion Products: Incomplete combustion products, Oxides of carbon

FLAMMABILITY PROPERTIES Flash Point [Method]: -103°C (-153°F) [ASTM D-92] Flammable Limits (Approximate volume % in air): LEL: 2.4 UEL: 9.5 Autoignition Temperature: 432°C (810°F)

SECTION 6 ACCIDENTAL RELEASE MEASURES

NOTIFICATION PROCEDURES In the event of a spill or accidental release, notify relevant authorities in accordance with all applicable regulations.

PROTECTIVE MEASURES Avoid contact with spilled material. Warn or evacuate occupants in surrounding and downwind areas if required, due to toxicity or flammability of the material. See Section 5 for fire fighting information. See the Hazard Identification Section for Significant Hazards. See Section 4 for First Aid Advice. See Section 8 for advice on the minimum requirements for personal protective equipment. Additional protective measures may be necessary, depending on the specific circumstances and/or the expert judgment of the emergency responders.

For emergency responders: Respiratory protection: half-face or full-face respirator with filter(s) for organic vapor or Self Contained Breathing Apparatus (SCBA) can be used depending on the size of the spill and potential level of exposure. If the exposure cannot be completely characterized or an oxygen deficient atmosphere is possible or anticipated, SCBA is recommended. Work gloves that provide chemical resistance and, when necessary, heat-resistance and/or thermal insulation are recommended. Note: gloves made of polyvinyl acetate (PVA) are not water-resistant and are not suitable for emergency use. Small spills: normal work clothes are usually adequate. Large spills: full body suit of chemical and thermal resistant material is recommended. Chemical goggles and face shield are recommended if contact with liquefied gas is possible.

SPILL MANAGEMENT Land Spill: Eliminate all ignition sources (no smoking, flares, sparks or flames in immediate area). Stop leak if you can do so without risk. CAUTION: When in contact with refrigerated/cryogenic liquids, many materials become brittle and are likely to break without warning. Allow liquid to evaporate from the surface. All equipment used when handling the product must be grounded. Do not direct water at spill or source of leak. Do not touch or walk through spilled material. If possible, turn leaking containers so that gas escapes rather than liquid. Isolate area until gas has dispersed. Prevent spreading of vapour through sewers, ventilation systems and confined areas. Use water spray to reduce vapour or divert vapour cloud drift. Avoid allowing water run-off to contact spilled material.

Water Spill: Eliminate all ignition sources (no smoking, flares, sparks or flames in immediate area). Allow liquid to evaporate from the surface. See Land Spill section of the SDS for advice on gases.

Water spill and land spill recommendations are based on the most likely spill scenario for this material; however, geographic conditions, wind, temperature, (and in the case of a water spill) wave and current direction and speed may greatly influence the appropriate action to be taken. For this reason, local experts should be consulted. Note: Local regulations may prescribe or limit action to be taken.

ENVIRONMENTAL PRECAUTIONS Prevent entry into waterways, sewers, basements or confined areas.

Product Name: COMMERCIAL PROPANE (NON ODORIZED) Revision Date: 22 Dec 2017 Page 5 of 11 ______

SECTION 7 HANDLING AND STORAGE

HANDLING Prevent exposure to ignition sources, for example use non-sparking tools and explosion-proof equipment. Use proper bonding and/or earthing procedures.However, bonding and earthing may not eliminate the hazard from static accumulation. Material can accumulate static charges which may cause an electrical spark (ignition source).

Static Accumulator: This material is a static accumulator.

STORAGE Ample fire water supply should be available. A fixed sprinkler/deluge system is recommended. The type of container used to store the material may affect static accumulation and dissipation. Keep container closed. Handle containers with care. Open slowly in order to control possible pressure release. Store in a cool, well- ventilated area. Outside or detached storage preferred. Storage containers should be earthed and bonded.

OTHER INFORMATION For the product itself:

May cause central nervous system disorder (e.g., narcosis involving a loss of coordination, weakness, fatigue, mental confusion and blurred vision) and/or damage. Exposure to rapidly expanding gas or vaporizing liquid may cause frostbite (cold burn). Exposure to this material, or one of its components, in situations where there is the potential for high levels, such as in confined spaces or with abuse, may result in abnormal heart rhythm (arrhythmia). High-level exposure to hydrocarbons (above occupational exposure limits) may initiate arrhythmia in a worker that is undergoing stress or is taking a heart-stimulating substance such as epinephrine, a nasal decongestant, or an asthma or cardiovascular drug. Simple asphyxiant: Acts by displacing oxygen in the lungs thereby diminishing the supply of oxygen available to the blood and tissues. Symptoms include shortness of breath, rapid heart rate, incoordination, lethargy, headaches, nausea, vomiting, and disorientation. Continued lack of oxygen may result in convulsions, loss of consciousness and death. Since exercise increases the tissue need for oxygen, symptoms will occur more quickly during exertion in an oxygen-deficient environment. Oxygen in enclosed spaces should be maintained at 21 percent by volume.

CMR Status: None.
